DTC Confirmation ProcedureEBS01FAE
CAUTION:
Always drive vehicle at a safe speed.
NOTE:

If DTC Confirmation Procedure has been previously conducted, always turn ignition switch OFF and wait
at least 10 seconds before conducting the next test.

Procedure for malfunction B is not described here. It takes extremely long time to complete procedure for
malfunction B. By performing procedure for malfunction A, the incident that causes malfunction B can be
detected.
TESTING CONDITION:
Steps 4 and 5 may be conducted with the drive wheels lifted in the shop or by driving the vehicle. If a
road test is expected to be easier, it is unnecessary to lift the vehicle.
WITH CONSULT-II
1. Start engine (EPS switch OFF).
2. Select “DATA MONITOR” mode with CONSULT-II.
3. Press MAIN switch and make sure that CRUISE indicator lights
up.
4. Drive the vehicle for at least 5 consecutive seconds under the
following condition.
If 1st trip DTC is detected, go to EC-390, "
Diagnostic Procedure"
.
If 1st trip DTC is not detected, go to the following step.
5. Drive the vehicle for at least 5 consecutive seconds under the following condition.
6. If 1st trip DTC is detected, go to EC-390, "
Diagnostic Procedure" .

DTC P1574 ASCD VEHICLE SPEED SENSOR

DTC P1574 ASCD VEHICLE SPEED SENSORPFP:31036
System DescriptionEBS01FF7
ECM receives two vehicle speed sensor signals via CAN communication line. One is sent from ESP/TCS/ABS
control unit (models with ESP) or “ABS actuator and electric unit (control unit)”(models without ESP), and the
other is from TCM (Transmission control module).
The ECM uses these signals for ASCD control. Refer to EC-529, "
AUTOMATIC SPEED CONTROL DEVICE
(ASCD)" for ASCD functions.
On Board Diagnosis LogicEBS01FAK
This self-diagnosis has the one trip detection logic.
The MI will not light up for this diagnosis.
NOTE:

If DTC P1574 is displayed with DTC U1000 or U1001, first perform the trouble diagnosis for DTC
U1000, U1001. Refer to EC-133, "
DTC U1000, U1001 CAN COMMUNICATION LINE" .

If DTC P1574 is displayed with DTC P0500, first perform the trouble diagnosis for DTC P0500.
Refer to EC-276, "
DTC P0500 VSS" .

If DTC P1574 is displayed with DTC P0605, first perform the trouble diagnosis for DTC P0605.
Refer to EC-283, "
DTC P0605 ECM" .
DTC Confirmation ProcedureEBS01FAL
CAUTION:
Always drive vehicle at a safe speed.
NOTE:
If DTC Confirmation Procedure has been previously conducted, always turn ignition switch OFF and wait at
least 10 seconds before conducting the next test.
TESTING CONDITION:
Step 3 may be conducted with the drive wheels lifted in the shop or by driving the vehicle. If a road test
is expected to be easier, it is unnecessary to lift the vehicle.
